Background
This file is for analysis of some data downloaded from The COVID Tracking Project on 20 August, 2020. This file contains data on positive tests, hospitalizations, deaths, and the like for coronavirus cases in the US. Data are unique by state and date.
Data Availability
The downloaded data file is read in as CSV, and the date column is converted to date format:

anyDuplicated()## [1] 0As expected, the file is unique by date and state. The date field has been converted from double to date. The main columns of interest will be:
- date
- state
- positiveIncrease - number of new positive cases for state during date
- deathIncrease - number of new deaths for state during date
A smaller frame containing only this data is created:
cvUse <- cvData %>%
select(date, state, cases=positiveIncrease, deaths=deathIncrease)
cvUse %>%

## <dbl> <dbl>
## 1 5546056 166127The numeric totals match those reported by the COVID Tracking Project for the same date. They are roughly 5% lower than the totals reported by worldometers.info. There are significant issues associated with official reporting for corornavirus, and a 5% discrepancy between sources is not unexpected.
The data are next checked for totals by state and by week:
cvUse %>%
group_by(state) %>%
summarize_if(is.numeric, sum) %>%
pivot_longer(-state) %>%
ggplot(aes(x=fct_reorder(state, value), y=value)) +
geom_col(fill="lightblue") +

labs(x="", y="", title="Coronavirus cases and deaths by epidemiological week through August 20, 2020")
Sort order by state generally matches published reports of coronavirus burden by state. The weekly data appear broadly aligned with other published data. The dip in the final week is due to only 5 of the 7 days of the week being included in the Thursday data file.
State population data (2015 estimates) are obtained from usmap for converting metrics to per capita, and the cvData file is filtered to only those observations contained in the state population file:
statePop <- usmap::statepop %>%

## 1 5516295 165742Over 99% of the cases and deaths are preserved when the territories and other non-state data are removed.
There appear to be at least two peaks in the case and death data, likely driven by different locales experiencing outbreaks at different times. Per capita cases and deaths by state are plotted:
# Per capita metrics by state
cvStatePerCapita <- cvUse %>%
group_by(state) %>%
summarize_if(is.numeric, sum) %>%
inner_join(statePop) %>%
mutate(cases=1000000*cases/pop_2015, deaths=1000000*deaths/pop_2015)## Joining, by = "state"# Disease burden by state, per capita
cvStatePerCapita %>%
ggplot(aes(x=cases, y=deaths)) +
geom_text(aes(label=state)) +
labs(x="Cases per million through August 20", y="Deaths per million through August 20")
States will be defined as having a low impact of disease if 1) deaths per million are 100 or less, and 2) cases per million are 10000 or less:
lowBurden <- cvStatePerCapita %>%
filter(deaths <= 100, cases <= 10000) %>%
pull(state)Next, the states that are not defined as low burden are hierarchically clustered, using total deaths per capita by week. Due to very significant expansions in testing volume both by state and within state over time, death data is likely more representative of disease burden by time than cases data. Deaths per capita by state by month are capped at 300 since otherwise the distance between the extremely high states (which is not so meaningful here) dominates the differences in early vs. late disease bruden:
# Calculate the raw data
clustData <- cvUse %>%
filter(!(state %in% lowBurden)) %>%
inner_join(statePop) %>%
mutate(month=lubridate::month(date), cpm=1000000*cases/pop_2015, dpm=1000000*deaths/pop_2015) %>%
filter(date >= as.Date("2020-03-15")) %>%
group_by(state, month) %>%

pivot_wider(state, names_from=month, values_from=c(dpm, cpm)) %>%
ungroup()## Joining, by = "state"# Run clusters without normalization, but with dpm limited to 300
distData <- clustData %>%
select(state, starts_with("dpm")) %>%
mutate_if(is.numeric, .funs=~pmin(., 300)) %>%
column_to_rownames("state")
cvTree <- hclust(dist(distData))
# Plot the dendrogram
plot(cvTree)
There appears to be a cluster of states that had early outbreaks, a cluster of states that had later outbreaks, and a large segment that falls in between these extremes. Suppose the dendrogram is split in to three clusters, with the low burden states added as a fourth cluster:
# Get the clusters from the tree, adding the low burden states as cluster 4
cvClusters <- c(cutree(cvTree, k=3),
rep(4, length(lowBurden)) %>% set_names(lowBurden)
)
# Add the clusters to the population data file
statePop <- statePop %>%

Metrics can be normalized by population to look at coronavirus burden per capita by segment over time:

geom_line() +

labs(x="", y="Rolling 7-day mean, per million", title="Rolling 7-day mean disease burden, per million")
Broadly speaking:
- Segment 4, which is small states with low coronavirus burden, may be experiencing a small rise in both cases and deaths
- Segment 3, which is much of the northeast plus MI, IL, and LA has a significant spike early followed by a rapid and largely sustained decline
- Segment 1, which is largely the south ex-LA/NM, appears to have peaked in cases by the middle of July and to be starting to decline in deaths as of the middle of August
- Segment 2, which is about half the country, appears similar to Segment 1 but with a much less pronounced spike in both cases and deaths in July/August
There appear to be meaningful differences in disease burden over time, and with a meaningful geographical explanatory component.
Next, the total volume of disease through August 20 is explored by state:

As expected, the segmentation approach has largely divided the states by total coronavirus burden. Mississippi and Arizona are in segment 1 due to the late nature of their outbreak.
Further, the data are explored for a combination of total disease burden and change over the past 30 days:

The clusters appear relatively well separated, with the possible exception of Louisiana which is arguably quite close to cluster 1. Cluster 3 stands out as having had a very high overall impact, but with not much of an increase in the past 30 days.
The individual trends by state are also plotted, smoothed by week:

With a few exceptions in a rather noisy segment 2 (as well as Louisiana in segment 3), states seem to broadly follow the disease state pattern for their cluster, though with some differences in magnitude and timing.
The process is converted to functional form so that it can be run using different data. First, a function is written to read in the data:

readCVData <- function(fileName,
showGlimpse=TRUE,
uqVars=c("date", "state"),

# showGlimpse: boolean, whether to run glimpse() on the file
# uqVars: variables that the file is expected to be unique by
# errDups: boolean, whether to error out if uniqueness is violated
# Read in the file and convert the 'date' from double to date
cvData <- readr::read_csv(fileName) %>%
mutate(date=lubridate::ymd(date))
# See a sample of the data
if (showGlimpse) glimpse(cvData)
# Check that the data are unique by date and state

Next, functions for creating and assessing clusters are created. The approach can use either hierarchical clustering or k-means, and focus on the following variables:
- Aggregate cases
- Aggregate deaths
- Shape of case curve (percentage by week/month)
- Shape of death curve (percentage by week/month)
Cases is a tricky clustering variable since detection rates were in the single-digit percentages early in the outbreak (estimates of ~50x as many infected as diagnosed). As testing volumes increased, it is likely that a greater percentage of cases are diagnosed. States that have later outbreaks appear to have many more cases per capita but with a lower death rate per capita:

At a glance, the segments appear reasonable:
- Segments 4 and 5 had early disease, but with less pronounced spikes in segment 5 than in segment 4, and with a greater case rebound in segment 5 than in segment 4
- Segments 2 had late disease, with little spike early
- Segments 1 and 3 have generally had fewer deaths, though with spiky cases that are similarly shaped if much lower than segment 2 (late disease, which may be increased testing finding a higher percentage of disease)

The process is easy to run and update now that it is in functional form. An exploration is made for 6 segments, which allows for a bucket of LA, DC, RI. These are states that had meaningful early disease spikes (though less than the main high-spike-early cluster) and also meaningful late disease spikes (though less than the main high-spike-late cluster). Findings include:
- There are significant differences (more than 10:1) in coronavirus deaths per capita by US state through August 20
- There is strong evidence that cases are significantly undercounted in aggregate, since almost all states have a calculated CFR that is well above the current best estimate of 0.5%
- The observed double-peak (“second wave”) in the US national data appears to be driven by different geographies (segments) having their first wave at different times; there has been a significant increase in testing, so deaths vs. cases in the late first waves are much less than they were in the early first waves
- While the segments are data-derived, there are significant qualitative similarities among many of the states assigned to a given cluster (e.g., south, Acela corrdior, central/upper plains, etc.)
- With the exception of segment 5, all segments have between 40 million and 80 million people
- Segment 2 (south plus AZ/NV) has a meaningful spike in cases and deaths in July/August; the spike in cases appears to be descending rapidly, with deaths plateaued if not decreasing
- Segment 4 (NY, NJ, CT, MA) has a meaningful spike in cases and deaths in March-May; the spikes appear to have descended to, and remained near, zero thereafter
- Segment 6 (IL, IN, MI, PA, MD, DE) had a meaningful spike in cases and deaths in March-May, though at under half the per capita levels of Segment 4; there has been a second spike of cases in July/August, though with little increase in deaths, suggestive that there may be increased testing more so than increased disease
- Segment 5 (LA, DC, RI) is something of a blend of Segment 4 and Segment 6; it has a higher spike early than Segment 6, but has a meaningful spike in cases late unlike Segment 4
- Segments 1 and 3 both have relatively low coronavirus burden, with segment 3 having greater cases than Segment 1 early, while segment 1 has greater cases than segment 3 late (Segment 1 is roughly a low-impact version of Segment 2, while Segment 3 is roughly a low-impact version of Segment 6)
The clusterStates() function is updated in two ways:
- Designed to output, at user’s request, a list containing the processed state-level data as well as the clustering object
- Designed to implement kmeans segmentation in addition to hierarchical clustering
An example is run using k-means, with 2 segments (the most obvious best silhouette width given these parameters):
# Test clusters that weight deaths heavily vs. cases and that weight shape more highly than total
# Using kmeans and testing for 1-10 clusters

Given the criteria that deaths matter much more than cases and that aggregate matters more than shape, the main clustering distinction is the 11 states plus DC that had early, heavy disease. While this produces the best mean silhouette width, it appears to be missing the distinction of states with a later spike. The elbow plot is consistent with this, as there is no obvious break where within-sum-squares meaningfully stops decreasing. Suppose that 5 segments are created, with the intent of splitting high/low deaths and early/late spikes:
# Test clusters that weight deaths heavily vs. cases and that weight shape more highly than total
# Using kmeans and testing for 1-10 clusters

The clusters appear very similar to those created using hierarchical clustering. A comparison of the segments assigned is made:
tibble::tibble(state=names(clustVec),
hier5=clustVec,
hier6=clustVec2,
km2=clustVec_km2,
km5=clustVec_km5
) %>%
count(hier6, hier5, km2, km5)## # A tibble: 10 x 5

## 7 4 4 1 5 4
## 8 5 5 1 3 3
## 9 6 5 1 3 5
## 10 6 5 2 3 1States are sufficiently differentiated, and the method sufficiently focused on deaths and aggregates, such that the clustering techniques produce similar results. There are many states that are near the edges of the clusters, and the choice of metrics and even random seeds will drive their assignments. Provided there are enough segments, there appears to typically be 1) at least one segment of early and heavy disease, 2) at least one segment of late and heavy disease, and 3) at least one segment of much lower than average disease. There is then some differentiation as to how the “early and heavy” and “lower than average” segments are identified and/or further subsetted.
The assessClusters() function is updated to put smaller versions of related plots all on a single page. Example usage is shown below:

There is at least some directional evidence that the hospitalized currently variables has been coming on line and that the hospitalized increase variable uses 0 for both NA and ‘no increase’. This would be problematic for using any of the variables (potentially other than hospCur) for cross-state comparisons. An analysis is run to see the frequency of NA by variable by date:

# Confirmation that hospitalized increase and nState are identical
sum(notNADate$hospitalizedIncrease != notNADate$nState)## [1] 0The plots confirm the meaningful gaps in the hospitalization, ICU, and ventilator data. Further, hospitalized increase exists and is non-missing for every case where there is a record (nState), suggesting that this metric has already had a filter such as ifelse(is.na(x), 0, x) applied. The only data that appears to grow from NA to potentially stable is ‘hospitalized currently’, which has become valid in all 51 states as of August.
General data availability by metric is:

## 45 31Prior to reporting hospitalizedCurrently, it appears that the hopitalized field and hospitalizedCumulative fields were identical for these states. And, hospitalizedIncrease appears to be the change in hospitalizedCumulative, which would be the number of people newly admitted to the hospital on that day (no reduction for any discharges/deaths on that day).
The lack of data will meaningfully complicate any cross-state comparisons, since some states did not report the same metrics (or at all) during times when their state had meaningful disease burden as shown by cases and deaths.
Since the ‘hospitalizedCurrently’ field is the most complete, a function is written to plot the per capita evolution of this metric by segment:
# Function to create plots of the number hospitalized by state and cluster
plotHospitalized <- function(df,
clusterVector,
dfState=stateData,
subT=""
) {
# FUNCTION ARGUMENTS:
# df: a data frame or tibble containing 'state', 'date', 'hospitalizedCurrently'
# clusterVector: a named vector of form 'state'='cluster'
# dfState: a state-level population file containing 'state' and 'pop'
# subT: a subtitle for the plot
# Create the key plotting data

For the segments hit early (2 and 4), there was at most a small time difference between the peak for cases, hospitalizations, and deaths. This is potentially driven by very limited testing, with many diagnoses being made when patients already had advanced disease. Segment 4 has had a reborund in cases but without any rebound in hospitalizations or deaths, suggesting that the recent spike in cases may be due to increased testing.
For the primary segment being hit late (1), there appears to be a 2-4 week gap between the peak in cases and hospitalizations and the peak in deaths. This is potentially driven by a larger number of cases being found early due to increased testing.
Segments 3 and 5 are near their peaks for cases and hospitalizations, while segment 3 (but not segment 5) is also near its peak for deaths. These segments have currently had a low burden on a per million basis, and the evolution of disease bruden in the following weeks or months is uncertain. Segment 3 across plots may be showing more indicia of a late spike like segment 1, while segment 5 across plots may be showing more indicia of a modest rebound in cases like segment 4.

There is increasing evidence that the primary late-outbreak segment is meaningfully past the peak and on the downswing, with the decline in deaths lagging the decline in cases and hospitalizations by a month or so. The primary early-outbreak states are not seeing much rebound in hospitalization or death, even as there has been a spike in cases (potentially near or even past plateau) in one of the segments. There is some evidence of spiking (cases and hospitalizations perhaps having peaked a month ago, deaths perhaps at or near peak now) of the mid-southern and western state segment that has generally seen low death rates from coronavirus.
The Ethical Skeptic creates interesting analyses of coronavirus, driven among other things by a search for consilience. Among the points raised are that PCR testing (for coronavirus and in other areas) has a high false-positive rate. As such, spikes in positive cases can be driven both by spikes in disease prevalence and spikes in testing. There are also meaningful lags in data reporting that can influence the timing of reported spikes.
These factors could contribute to the observation that increases in hospitalizations and deaths sometimes, but not always, follow increases in positive test results. It may also contribute to the observation that deaths no longer spike anywhere near as high for a given spike in positive cases as they did in March-May.
Next steps are to explore the evolution of reported tests (positive and negative) by cluster as well as the adjustment methodology used in the TES consilience plots (attempting to normalize reported positive cases so that a number of cases reported in April and the same number of cases reported in August represent the same level of disease prevalence).
There are many variables related to testing available in the COVID Tracking Project files:

Most of the tests are based on the source ‘posNeg’, and most are of type ‘totalTestsViral’.
The COIV Tracking Project API notes that fields ‘negative’ is a column that reports the total number of people with a negative test result. Since a person can test negative many times, this is not necessarily reflective of testing volume.
The ‘totalTestResults’ column (and therefore ‘totalTestResultsIncrease’) is heterogeneous data that cannot be easily compared across states. It is either ‘posNeg’ (sum of positive and negative) or ‘totalTestEncountersViral’.
The ‘totalTestsViral’ column is listed as being the total number of PCR tests. It may in a handful of cases include antigen tests.
The ‘totalTestEncountersViral’ column is listed as being the total number of people who underwent PCR testing in a given day (multiple tests to the same person on the same day counted as only 1).

Next, availability of data by state over time is assessed:
# Not NA data
notNADateStateTests <- dfRaw_20200830 %>%
filter(state %in% c(state.abb, "DC")) %>%
select_at(vars(all_of(c("state", "date", testNames)))) %>%
mutate(nState=1, month=lubridate::month(date)) %>%
group_by(month, state) %>%
summarize_if(is.numeric, .funs=function(x) { min(!is.na(x))}) %>%
ungroup()
# Evolution of Not NA states by month
notNADateStateTests %>%
pivot_longer(-c(state, month)) %>%
filter(!(name %in% c("nState"))) %>%
ggplot(aes(y=fct_reorder(state, value, .fun=sum), x=month)) +
geom_tile(aes(fill=value)) +
labs(x="", y="", title="Evolution of data availability by metric") +
scale_fill_continuous("", low="white", high="green") +
facet_wrap(~name, nrow=1)
So, while the field is heterogeneous, data availability may suggest use of ‘totalTestResultsIncrease’ as a general proxy for the testing volume occurring over time. The evolution is as follows:
dfRaw_20200830 %>%
group_by(date) %>%
summarize(tests=sum(totalTestResultsIncrease, na.rm=TRUE)) %>%
ungroup() %>%
arrange(date) %>%
helperRollingAgg(origVar="tests", newName="tests7") %>%
ggplot(aes(x=date, y=tests7)) +
geom_line() +
labs(x="Month", y="Daily tests (rolling 7-day mean", title="Rolling 7-day mean tests per day") +
scale_x_date(date_breaks="1 months", date_labels="%m")## Warning: Removed 6 rows containing missing values (geom_path).
The metric can also be assessed on a per capita basis by segment:
dfRaw_20200830 %>%
select(state, date, totalTestResultsIncrease) %>%
inner_join(stateData, by="state") %>%
mutate(cluster=factor(clustVec[state])) %>%
mutate(tpm=1000000*totalTestResultsIncrease/pop) %>%
group_by(state) %>%
arrange(date) %>%
helperRollingAgg(origVar="tpm", newName="tpm7") %>%
ungroup() %>%
helperTotalvsElements(keyVar="tpm7",
title="Evolution of tests by segment",
mapper=c("tpm7"="Tests per million per day (7-day rolling mean"),
facetScales="free_y"
)
Testing appears to have grown rapidly in all segments, though with a significant decline in testing in the “late spike” states that is associated with the same timing as the fall in cases in “late spike” states.
Most segments appear to be reporting 2000 tests per 1 million population. At a false positive rate of 1%, this would produce 20 false-positive tests per million. The New England and Mid-Atlantic states are reporting case-per-million numbers of aound this magnitude, which is suggestive that they may be catching mostly false positives rather than disease prevalence. This would be consisent with the hospitalization and deaths data being extremely low currently in these segments.
Further exploration will focus on integrating testing data with the other key metrics (cases, hospitalizations, deaths) for the overall process.
The data are run through the main preparation and assessment functions:
# STEP 1: Filter the data so that it includes tests
varsFilter_002 <- c("date", "state", "positiveIncrease", "deathIncrease",
"hospitalizedCurrently", "totalTestResultsIncrease"

The consolidated data can then be used to assess the positive rate for any given state and date:
# Create percent positive by state-date
consPositive <- consolidatedPlotData_20200830_002 %>%
ungroup() %>%
select(state, cluster, date, name, vpm7) %>%
arrange(state, cluster, date, name) %>%

pivot_longer(-c(state, cluster, date), values_to="vpm7") %>%

# Plot at segment level

ggplot(aes(x=date, y=vpm7)) +
geom_line(aes(group=cluster, color=cluster), lwd=1) +

labs(x="Month", y="Percent positive (rolling 7-day mean)", title="Positive test rates by cluster") +
geom_hline(yintercept = 0.01, lty=2, lwd=0.5)
# Plot at state level, facetted by segment
consPositive %>%
filter(name=="pctpos", vpm7 <= 1, vpm7 >= 0) %>%
ggplot(aes(x=date, y=vpm7)) +
geom_line(data=~filter(., state=="cluster"), aes(group=cluster, color=cluster), lwd=1.5) +
geom_line(data=~filter(., state!="cluster"), aes(group=state), alpha=0.25) +
scale_x_date(date_breaks="1 months", date_labels="%m") +
labs(x="Month", y="Percent positive (rolling 7-day mean)",
title="Positive test rates by state and cluster"
) +
geom_hline(yintercept = 0.01, lty=2, lwd=0.5) +
facet_wrap(~cluster)
The segment that was hit hardest early is down around a 1% test positive rate (dotted line on the plots) on a large volume of tests. This is in the range that literature suggests as the false-positive rate for PCR testing. The segment that was hit hardest late still has test positive rates over 10%, suggestive that there is still meaningful disease being diagnosed.
Of note, the outbreaks that hit early were associated with sustained test positive rates in the 30%+ range while the other states have generally been under 20% test positive rates. This is consistent with the observation that there are far fewer hospitalizations and deaths per capita in the late segment, even as the total number of cases in the last segment surpass those of the early segments.
Cumulative metrics can be of interest also. There is no solid metric for cumulative hospitalizations, but the cases, deaths, and tests data can be converted to cumulative:
# Create the cumulative data
clusterCumulative <- consPositive %>%
filter(name %in% c("cases", "deaths", "tests"), !is.na(vpm7)) %>%
arrange(state, cluster, name, date) %>%
group_by(state, cluster, name) %>%
mutate(cum7=cumsum(vpm7)) %>%
ungroup()
# Plot the cumulative data by cluster
clusterCumulative %>%
filter(state=="cluster") %>%
ggplot(aes(x=date, y=cum7)) +
geom_line(aes(group=cluster, color=cluster)) +
facet_wrap(~name, nrow=1, scales="free_y") +
scale_x_date(date_breaks="1 months", date_labels="%m") +
labs(x="Month", y="Cumulative Burden (per million)",
title="Cumulative burden by segment (per million)"
)
# Find top-5 states in either total deaths per capita or increase in deaths per capita in the past 30 days
stateRanks <- clusterCumulative %>%

group_by(state) %>%
summarize(max7=max(cum7), tminus30=sum(ifelse(date==max(date)-lubridate::days(30), cum7, 0))) %>%
ungroup() %>%
mutate(growth=max7-tminus30, rkTotal=min_rank(-max7), rkGrowth=min_rank(-growth),
flag=ifelse(pmin(rkTotal, rkGrowth)<=5, 1, 0)
) %>%
arrange(-flag, rkTotal)
flagStates <- stateRanks %>%
filter(flag==1) %>%
pull(state)
# Plot the cumulative deaths data by state
# Bold for 5-highest total and 5-highest 1-month increase
clusterCumulative %>%
filter(state!="cluster", name=="deaths") %>%
mutate(bold=ifelse(state %in% flagStates, 1, 0)) %>%
ggplot(aes(x=date, y=cum7)) +

aes(x=date+lubridate::days(10), label=paste0(state, ": ", round(cum7, 0)), color=cluster),
size=3, fontface="bold"
) +
scale_x_date(date_breaks="1 months", date_labels="%m") +
scale_alpha_identity() +
scale_size_identity() +
labs(x="Month", y="Cumulative Deaths (per million)",

Louisiana and Mississippi stand out as having more sustained outbreaks than the other top-death states. Most of the other states with high deaths had a sharper slope change associated around the time of their main outbreak. This is consistent with MS and (especially) LA tending to be poorly associated with the trends of the other states in their cluster.
The above approach is converted to a function so it can be repeated:
# Function to convert a file to cumulative totals
makeCumulative <- function(df,
typeVar="name",
typeKeep=c("cases", "deaths", "tests"),
valVar="vpm7",
groupVars=c("state", "cluster", "name"),
arrangeVars=c("date"),
newName="cum7"
) {
# FUNCTION ARGUMENTS:
# df: data frame containing the metrics
# typeVar: the variable holding the metric type (default is 'name')
# typeKeep: the values of typeVar to be kept
# valVar: the variable holding the metric value (default is 'vpm7')
# groupVars: groups for calculating cumulative sum
# arrangeVars: variables to be sorted by before calculating cumulative sum
# newName: the name for the new variable
# Create the cumulative data
dfCum <- df %>%
filter(get(typeVar) %in% typeKeep, !is.na(get(valVar))) %>%
arrange_at(vars(all_of(c(groupVars, arrangeVars)))) %>%
group_by_at(groupVars) %>%
mutate(!!newName:=cumsum(get(valVar))) %>%
ungroup()
# Return the processed data
dfCum
}
clCum <- makeCumulative(consPositive)
identical(clCum, clusterCumulative)## [1] TRUEAs expected, the function produces the same results as the stand-alone code.
Next, a function is written to identify the states to flag:
# Function to find and flag states that are high on a key value or change in key value
findFlagStates <- function(df,
keyMetricVal,
keyMetricVar="name",
cumVar="cum7",
prevDays=30,
nFlag=5
) {
# FUNCTION ARGUMENTS:
# df: the data frame containing the cumulative data
# keyMetricVal: the metric of interest (e.g., "deaths", "cases", "tests")
# keyMetricVar: the variable name for the column containing the metric of interest
# cumVar: variable containing the cumulative totals
# prevDays: the number of days previous to use for defining growth
# nFlag: the number of states to flag for either total or growth (top-n of each)
# Find top-5 in either total or recent increase
dfFlag <- df %>%
filter(get(keyMetricVar)==keyMetricVal, state!="cluster") %>%
select_at(vars(all_of(c("state", "date", cumVar)))) %>%
group_by(state) %>%
summarize(maxVal=max(get(cumVar)),
tminus=sum(ifelse(date==max(date)-lubridate::days(prevDays), get(cumVar), 0))
) %>%
ungroup() %>%
mutate(growth=maxVal-tminus,
rkTotal=min_rank(-maxVal),
rkGrowth=min_rank(-growth),
flag=ifelse(pmin(rkTotal, rkGrowth)<=nFlag, 1, 0)
) %>%
arrange(-flag, rkTotal)
# Return the top values as a vector of states
dfFlag %>%
filter(flag==1) %>%
pull(state)
}
identical(flagStates, findFlagStates(clCum, keyMetricVal = "deaths"))## [1] TRUEAs expected, the function flags the same states when applied using deaths.
Lastly, a function is written to make the plots, once by cluster and once by state with flagging:
# Function to plot cumulative data
plotCumulativeData <- function(df,
keyMetricp2,
flagsp2,
p2Desc=keyMetricp2,
keyVar="cum7",
makep1=FALSE,
makep2=TRUE
) {
# FUNCTION ARGUMENTS:
# df: the data frame of cumulative data
# keyMetricp2: the key metric to be plotted in the second plot (e.g., "deaths", "cases", "tests")
# flagsp2: states to be treated as flagged in the second plot
# p2Desc: the description to be used in plot 2
# keyVar: the key variable to plot
# makep1: boolean, whether to make the first plot
# makep2: boolean, whether to make the second plot
# Plot the cumulative data by cluster (if flag is set for producing this)
if (isTRUE(makep1)) {
p1 <- df %>%
filter(state=="cluster") %>%
ggplot(aes(x=date, y=get(keyVar))) +
geom_line(aes(group=cluster, color=cluster)) +
facet_wrap(~name, nrow=1, scales="free_y") +
scale_x_date(date_breaks="1 months", date_labels="%m") +
labs(x="Month",
y="Cumulative Burden (per million)",
title="Cumulative burden by segment (per million)"
)
print(p1)
}
# Plot the cumulative totals over time for one metric, and flag the highest
if (isTRUE(makep2)) {
p2 <- df %>%
filter(state!="cluster", name==keyMetricp2) %>%
mutate(bold=ifelse(state %in% flagsp2, 1, 0)) %>%
ggplot(aes(x=date, y=get(keyVar))) +
geom_line(aes(group=state, color=cluster, alpha=0.4+0.6*bold, size=0.5+0.5*bold)) +
geom_text(data=~filter(., bold==1, date==max(date)),
aes(x=date+lubridate::days(10),
label=paste0(state, ": ", round(get(keyVar), 0)),
color=cluster
),
size=3,
fontface="bold"
) +
scale_x_date(date_breaks="1 months", date_labels="%m") +
scale_alpha_identity() +
scale_size_identity() +
labs(x="Month",
y=paste0("Cumulative ", p2Desc, " (per million)"),
title=paste0("Cumulative coronavirus ", p2Desc, " by state (per million)"),
subtitle="Top 5 states for total and growth rate are bolded and labelled"
)
print(p2)
}
}
# Facetted plot
plotCumulativeData(clCum, keyMetricp2="", flagsp2="", makep1=TRUE, makep2=FALSE)
# Plots by state for death, cases, tests
plotCumulativeData(clCum,
keyMetricp2="deaths",
flagsp2=findFlagStates(clCum, keyMetricVal = "deaths")
)
plotCumulativeData(clCum,
keyMetricp2="cases",
flagsp2=findFlagStates(clCum, keyMetricVal = "cases")
)
plotCumulativeData(clCum,
keyMetricp2="tests",
flagsp2=findFlagStates(clCum, keyMetricVal = "tests")
)
Results are generally as expected.
The site USA Facts makes data available for coronavirus cases and deaths by county. Data are provided with one row per county and one column for each date. As of September 1, the site reports 6.02 million cases and 183 thousand deaths, roughly aligned with the 5.93 million cases and 175 thousand deaths as of August 29 in the COVID Tracking Project data. Counting cases and deaths is an inexact science and differences of ~5% are not uncommon based on different standards for counting a “case” or a “death” due to coronavirus.
The data are read in:

At a glance, there are minor differences by state, most accounting for a handful of percent or less. Nothing appears likely to impact the analysis.
The same analysis is run for deaths:

The difference in deaths is driven largely by New York, where USA Facts reports ~7000 more deaths (~25% of the baseline deaths) than COVID Tracking Project. Most other states are fairly well aligned between the data sources, and the caution is noted that conclusions focused on New York (standalone or segment) may be heavily influenced by selection of data source.
Evolution of deaths and cases over time is also assessed:

The plots provide further evidence that the sources are well aligned with the exception of New York state. There is some directional evidence that COVID Tracking Project reports deaths earlier than USA Facts, though a cumuluative difference of 500 deaths will have modest if any impact on the analysis.

USA Facts appear to be using more recent estimates of US population which include a generally larger population and with different states gaining or losing population at different rates.
Next steps are to explore the coronavirus burden by county using the USA Facts data.
A handful of states assign meaningful amounts of disease burden to “unassigned”:
unassignedState <- pvtCases_20200903 %>%

pivot_longer(c("cases", "deaths")) %>%
group_by(state, name) %>%

ggplot(aes(x=fct_reorder(state, unass*ifelse(name=="cases", 1, 0)), y=unass)) +
geom_point() +
geom_text(data=~filter(., (name=="cases" & unass >= 0.02) | (name=="deaths" & unass > 0.005)),
aes(y=unass + ifelse(name=="cases", -0.0025, -0.001),

labs(x="", y="% Unassigned as of August 29, 2020", title="Unassigned percentage by state") +

These amounts appear to be modest overall and unlikely to meaningfully drive macro-level findings. Perhaps an algorithm can be considered for assigning cases to counties in proportion to total burden and/or population by county in the assigned portion of the state.
Four states hit hard on a per capita basis are in the northern Acela corridor - NJ, NY, CT, MA. A graph is created for the per capita death rate and disease rate in these geographies, with RI, VT, and NH added since they are contiguous. Data in the unassigned bucket are not included:

There is significant variation in disease burden by county, with many of the more rural counties having a modest coronavirus burden per capita relative to the more densely populated areas.
The data are then pulled using the function without plotting:

The hardest hit counties are in the NYC metro area and have deaths per capita in the 0.2%-0.35% range. The disases is estimated to have a fatality rate of 0.25%-0.50% (though with a lot of uncertainty), so there is some evidence that a large percentage of these areas may have contracted coronavirus if the reported death data and fatality rates are accurate.
The functions are further integrated so they can be repeated for different geographies:

There is a very different slope of deaths vs. cases that seems to be consistent across counties, particularly for the segment that was hit early and hard. There is a significant difference in the median county-level burden and the overall segment-level burden, suggestive that heavier outbreaks in larger counties may play a role. Notably, the southern states that have been hit late have similar metrics whether reported as the median by county or aggregate by segment, potentially suggestive of a lesser population-driven impact in this segment.
With some modifications, the clusterStates() function can be used to cluster the county-level data:
- Set the countyFIPS variable as ‘state’ and keep only fields date, state, dpm, cpm
- Convert the county-level data to daily totals rather than cumulative daily counts
- Restrict to counties with population of at least x (likely in the range of 25k)

Running with 5 clusters provides a segment with very high disease early, a segment with high disease late, two segments with mild-moderate disease (one early, one late), and one segment with low disease.
The assessClusters() function has been updated to (in a klunky manner) accept county-level data and produce basic charts:
# Check how 5 clusters look
clustVec_county_km_test <- countyCluster_km_test$objCluster$cluster
plotData_county_km_test <- assessClusters(clustVec_county_km_test,

A handful of counties with under 10% of the US population were hit very hard and early with high per-capita deaths rates. While there have been surges in other counties, peaks in daily deaths per capita are roughly 25% or less of what the early-hard segment experienced.
Next steps are to further customize assessClusters() to allow for plotting the elements of county-level data (the line per county, as used with states, is messy and uninformative; an aggregate statistic such as 90% range is needed for sensible plotting).
The function has been updated, and is now incorporated in the results above. Next steps are to further explore the attributes of the county-level segments and impact of different numbers of segments.
Two preliminary steps will help for running multiple scenarios with county-level segments:
- Create a helper function for calling assessClusters() from county-level inputs
- Update assessClusters() such that its components are each themselves a separate function (and can then be called using boolean arguments)
First, the helper function is created:
# Function for calling assessClusters() for county-level segments
helperAssessCountyClusters <- function(vecCluster,
dfPop,
dfBurden,
dfPopGeoVar="state",
dfPopPopVar="population",
...
) {
# FUNCTION ARGUMENTS:
# vecCluster: the named cluster vector
# dfPop: the data frame containing the population data
# dfBurden: the data frame containing the burden statistics by county and date
# ...: other arguments to pass to assessClusters()
# Run the process
plotAssess <- assessClusters(vecCluster,
dfState=dfPop %>%
group_by_at(dfPopGeoVar) %>%
summarize(pop=mean(get(dfPopPopVar))) %>%
ungroup(),
dfBurden=select(dfBurden, -population),
isCounty=TRUE,
...
)
# Return the plot object
plotAssess
}
# Test the function on the same data as before
helperACC_test <- helperAssessCountyClusters(countyCluster_km_test$objCluster$cluster,
dfPop=countyFiltered,

While k-means results are highly dependent on starting conditions (seed), some general trends are observed:
- The first cluster (n=2) breaks apart the counties with very high and early deaths from all other counties. There are ~200 counties with ~20% of the US population that account for ~60% of the deaths through August
- The third cluster breaks apart the “lower disease” counties in to a group that experienced a (relatively) small surge in deaths late and a group that experienced a (relatively) small surge in deaths early
- The fourth cluster separates counties that have consistently had very few deaths per capita
- The fifth cluster separates counties that have had relatively sustained deaths both early and late
- Clusters 6-8 are rather noisy and challenging to classify in a sentence or two; consistently, the coutnies hit heavy and early get split in to a smaller group with a bigger spike as segments increase
Five segments appears to be a sweet spot qualitatively:
- Counties with early, high death per capita
- Counties with early, moderate death per capita
- Counties with sustained, moderate death per capita
- Counties with late, moderate death per capita
- Counties with low death per capita
Of interest, there does not appear to be a segment with late an high death. The small number of populous counties hit early tend to be the primary locations with the highest death rates.
Suppose that two additional plots are created to show cumulative disease burden per capita by segment:
# Test the function on the same data as before, with the plots each on their own page

facet_wrap(~c("cases"="Cases per million", "deaths"="Deaths per million")[name], scales="free_y") +
scale_x_date(date_breaks="1 months", date_labels="%b", expand=expand_scale(c(0, 0.1)))
The segments have had very different experienced with the disease, ranging from 100 deaths per million in counties covering ~20% of US population to 1000-2000 deaths per million in counties covering ~15% and ~10% respectively of US population. The remaining counties covering ~60% of US population have ~400 deaths per million.
How well do the county segments explain some of the differences observed by state? For example, NY/NJ had heavy and early disease, LA has had sustained disease, and FL/GA has had moderate and late disease:
stateCombos <- list(c("NY", "NJ", "CT", "RI", "VT", "MA", "NH", "PA"), c("LA"), c("FL", "GA", "AL"))
fipsCounty <- helperACC_test_04 %>%
mutate(state=stringr::str_pad(state, width=5, side="left", pad="0")) %>%
count(state, cluster) %>%
select(fips=state, cluster)
for (x in stateCombos) {
p1 <- usmap::plot_usmap(regions="counties", include=x, values="cluster", data=fipsCounty) +
scale_fill_discrete("Cluster", limits=c(1:5)) +
labs(title=paste0("County clusters for states: ", paste0(x, collapse=", ")))
print(p1)
}
- Florida stands out as having a few populaous counties in the “sustained” segment while most of the other counties are late. Georgia by contrast has a meaningful number of populous coutnies that fall in the early but moderate segment, consistent with Georgia having seen less of a late spike in deaths than Florida
- Most counties in Louisiana have had sustained disease, consistent with the state as a whole
- The northeast and especially New York stands out for significant geographical variation
- Counties close to NYC are almost all early and hard, while NYS counties outside the NYC metro area are almost exclusively a mix of early and moderate or sustained low death rates
- By contrast, NJ outside the NYC metro and MA both have primarily counties that have experienced sustained, moderate disease
- The Philadelphia area counties have experienced sustained, moderate disease while the rest of the PA looks much like the non-NYC-metro portions of NYS
Next steps are to explore the evolution of deaths by state and cluster.

# Run for East North Central region
stateCountySummary(usmap::.east_north_central)
The population differences by segment are consistent with the general trends observed by state. Next steps are to add the cumulative deaths per million curve.
The function has been updated to optionally show cumulative deaths by segment:
# Create cumulative for NY
stateCountySummary(states=c("NY"), showQuadrants=FALSE, showCumulative=TRUE)
# Create cumulative for FL-GA
stateCountySummary(states=c("FL", "GA"),
showQuadrants=FALSE,
showCumulative=TRUE,
facetCumulativeByState=TRUE
)
# Create cumulative for LA-MS-AL
stateCountySummary(states=c("LA", "MS", "AL"),
showQuadrants=FALSE,
showCumulative=TRUE,
facetCumulativeByState = TRUE
)
# Run for East North Central region
stateCountySummary(states=usmap::.east_north_central,
showQuadrants=FALSE,
showCumulative=TRUE,
facetCumulativeByState = TRUE
)
Next steps are to control the color palette so the same colors are used even when a level of the factor is not present in the data.
The option drop=FALSE inside the scale_*_discrete(drop=FALSE) appears to achieve this. Further, it would be useful to convert the levels of the factor so that they consistently go from most to least disease on a cumulative basis. The refactoring can be performed as:
# Function to reorder and relabel factors
changeOrderLabel <- function(df,
fctVar="cluster",
grpVars=c(),
burdenVar="dpm",
wgtVar="pop",
exclfct="999"
) {
# FUNCTION ARGUMENTS
# df: the data frame
# fctVar: the factor variable
# grpVars: the variable that the data are aurrently at (e.g., "fipsCounty" for county-level in df)
# burdenVar: the disease burden variable for sorting
# wgtVar: the weight variable for sorting
# exclfct: the factor lele to be excluded from analysis
# General approach
# 1. Data are aggregated to c(fctVar, grpVars) as x=sum(burdenVar*wgtVar) and y=mean(wgtVar)
# 2. Data are aggregated to fctVar as z=sum(x)/sum(y)
# 3. Factors are reordered from high to low on z, with the excluded factor added back last (if it exists)
# Check if exclfct exists in the factor variable
fctDummy <- exclfct %in% levels(df[, fctVar, drop=TRUE])
# Create the summary of impact by segment
newLevels <- df %>%
filter(get(fctVar) != exclfct) %>%
group_by_at(vars(all_of(c(fctVar, grpVars)))) %>%
summarize(x=sum(get(burdenVar)*get(wgtVar)), y=mean(get(wgtVar))) %>%
group_by_at(vars(all_of(fctVar))) %>%
summarize(z=sum(x)/sum(y)) %>%
arrange(-z) %>%
pull(fctVar) %>%
as.character()
# Add back the dummy factor at the end (if it exists)
if (fctDummy) newLevels <- c(newLevels, exclfct)
# Reassign the levels in df
df %>%
mutate(!!fctVar:=factor(get(fctVar), levels=newLevels, labels=newLevels))
}And, the plots can use all factor levels by enforcing drop=FALSE inside an appropriate scale_color_ or scale_fill_ object. This has been updated for:
- stateCountySummary()
And, the evaluation process can be run using the updated functions:
# Run for select upper midwest states
stateCountySummary(states=c("MN", "ND", "SD", "WI"),
df=changeOrderLabel(fullStateData, grpVars="fipsCounty"),
showQuadrants=TRUE,
showCumulative=TRUE,
facetCumulativeByState = TRUE,
showAllFactorLevels = TRUE
)
And since the reordering makes for easier plot interpretation, the other summaries are also re-run:
# Create cumulative for NY
stateCountySummary(states=c("NY"),
df=changeOrderLabel(fullStateData, grpVars="fipsCounty"),
showQuadrants=TRUE,
showCumulative=TRUE
)
# Create cumulative for FL-GA
stateCountySummary(states=c("FL", "GA"),
df=changeOrderLabel(fullStateData, grpVars="fipsCounty"),
showQuadrants=TRUE,
showCumulative=TRUE,
facetCumulativeByState=TRUE
)
# Create cumulative for LA-MS-AL
stateCountySummary(states=c("LA", "MS", "AL"),
df=changeOrderLabel(fullStateData, grpVars="fipsCounty"),
showQuadrants=TRUE,
showCumulative=TRUE,
facetCumulativeByState = TRUE
)
# Run for East North Central region
stateCountySummary(states=usmap::.east_north_central,
df=changeOrderLabel(fullStateData, grpVars="fipsCounty"),
showQuadrants=TRUE,
showCumulative=TRUE,
facetCumulativeByState = TRUE
)
And, the main cluster summary plots are reproduced also, with the factors reordered:
# Get the desired cluster order
clustOrder <- changeOrderLabel(fullStateData, grpVars="fipsCounty") %>%
filter(cluster!=999) %>%
pull(cluster) %>%
fct_drop() %>%
levels()
# Test the function on the same data as before, with the plots each on their own page
dummy_Data_NotUse <- helperAssessCountyClusters(factor(countyCluster_km_test$objCluster$cluster,
levels=clustOrder
),
dfPop=countyFiltered,
dfBurden=countyFiltered,
thruLabel="Sep 3, 2020",
plotsTogether=TRUE,
showMap=FALSE
)
##
## Recency is defined as 2020-08-02 through current
##
## Recency is defined as 2020-08-02 through current
This requires using an output as an input as a workaround. Next steps are to update assessClusters() and ancillary functions to include arguments for auto-creation of proper cluster levels as part of the routine.
The assessClusters() function has been updated to allow for ordering of clusters by deaths per million. Updated summaries are produced with the relevant argument:
helperACC_test_05 <- helperAssessCountyClusters(countyCluster_km_test$objCluster$cluster,
dfPop=countyFiltered,
dfBurden=countyFiltered,
thruLabel="Sep 3, 2020",
plotsTogether=TRUE,
showMap=TRUE,
clusterPlotsTogether=TRUE,
orderCluster=TRUE
)
##
## Recency is defined as 2020-08-02 through current
##
## Recency is defined as 2020-08-02 through current
The clusters are now in a consistent order from highest to lowest aggregate disease burden.
Further, a function is written to create the integrated county data for plotting in the stateCountySummary() function:
# Create the cluster-state data
helperMakeClusterStateData <- function(dfPlot,
dfPop=usmap::countypop,
dfBurden=countyDailyPerCapita,
orderCluster=FALSE
) {
# FUNCTION ARGUMENTS:
# dfPlot: the raw plotting data (which can have factors already reordered)

The segments appear to be reasonable with the new county-level data. Next steps are to check the alignment of peaks (shapes) in cases and deaths by national and sub-national levels.
As an initial exploratory step, the curves for cases and deaths by cluster are superimposed, with the scale modified such that 100 represents the 7-day peak of the data:
clusterNorm <- helper_test_20200917 %>%
group_by(cluster, date) %>%
summarize(cpm7=sum(pop*cpm7)/sum(pop), dpm7=sum(pop*dpm7)/sum(pop), pop=sum(pop)) %>%
group_by(cluster) %>%
mutate(caseNorm=100*cpm7/max(cpm7, na.rm=TRUE), deathNorm=100*dpm7/max(dpm7, na.rm=TRUE)) %>%
ungroup()
clusterNorm %>%
select(cluster, date, caseNorm, deathNorm) %>%
pivot_longer(-c(cluster, date)) %>%
filter(!is.na(value)) %>%
ggplot(aes(x=date,
y=value,
color=c("deathNorm"="Normalized Death", "caseNorm"="Normalized Cases")[name],
group=name
)
) +
geom_line() +
facet_wrap(~cluster) +
scale_color_discrete("Metric") +
scale_x_date(date_breaks="1 months", date_labels="%m") +
labs(x="2020",
y="Normalized Burden",
title="Burden by Segment",
subtitle="Normalized (100 is segment maximum for metric)"
)
There are significant differences in behavior with early epidemic and late epidemic:
- Ealy epidemic had less time between case spikes and death spikes, potentially due to cases being diagnosed at a more advanced stage
- Death rates were higher earlier, such that segments with two spikes in cases have a much larger spike in deaths at the early spike (normalizes to 100) than the later spike
Next steps are to begin quantifying the lag factor and ratio, focused for now on the cluster-level data
Suppose that the “early pandemic” is defined as March-May and an attempt is made to best line up the shapes of the curves during that time period:
clusterNorm %>%
select(cluster, date, caseNorm, deathNorm) %>%
pivot_longer(-c(cluster, date)) %>%
filter(!is.na(value), date>="2020-03-01", date<="2020-05-31") %>%

The two segments with early disease show stronger correlations between deaths and cases with a bit of a lag. The best lag time for each cluster is identified:
bestLag <- corrLagEarly %>%
group_by(cluster) %>%
filter(corr==max(corr)) %>%
ungroup()
bestLag## # A tibble: 5 x 3
## cluster corr lag
## <fct> <dbl> <int>
## 1 5 0.971 2
## 2 2 0.809 4
## 3 1 0.937 5
## 4 4 0.972 7
## 5 3 0.989 8There is roughly a 1-week lag between cases and deaths in the early pandemic. The ratio of deaths to cases can then be calculated on the lag data:
clusterMarchMay %>%
inner_join(bestLag, by="cluster") %>%
group_by(cluster) %>%
arrange(date) %>%
mutate(cpmlag=lag(cpm7, min(lag))) %>%
filter(!is.na(cpmlag)) %>%
mutate(ratCur=dpm7/cpmlag, ratCum=cumsum(dpm7)/cumsum(cpmlag)) %>%

) +
geom_text(data=~filter(., date==max(date)),
aes(label=paste0(round(100*ratCum, 1), "%"), y=ratCum+0.02)
) +
facet_wrap(~cluster)
In the heavier hit early clusters, there was roughly a one-week lag between cases and deaths, and deaths ran between 5% and 10% of cases. The segments that were not hit as heavy generally showed a lower number of deaths relative to cases.
Next steps are to generalize the approach so that it can be applied to different geographies and timings:

Lags for segments with late disease appear to be in the 3-week range, suggestive that cases may be diagnosed earlier in the late pandemic. Fatality rates are generally much lower in the ‘late disease’ segments also, in the 1%-2% range rather than the previously observed 5%-10% range. This is consistent with expanded testing finding more cases of mild disease, a hypothesis that has been piublicly floated.
Next steps are to drill down to various levels such as specific counties.
